GB/T 15306.3-2008 in English

《GB/T 15306.3-2008陶瓷可转位刀片 第3部分：无孔刀片尺寸（U级）》由TC91（全国刀具标准化技术委员会）归口，主管部门为中国机械工业联合会。
GB/T15306的本部分规定了刀尖倒圆、无固定孔、法向后角为0°、精度为U 级、用陶瓷切削材料制成的可转位刀片的尺寸。这些刀片主要从顶部夹紧在车刀和镗刀刀杆上。
本部分适用于用各种陶瓷切削材料制成的U 级无孔可转位刀片。
陶瓷切削材料由各种不同的氧化物、氮化物和碳化物及金属等组成。例如,这类陶瓷材料有:氧化物陶瓷(主要由氧化铝Al2O3 组成)、氧化物�蔡蓟�物陶瓷(主要由氧化铝和其他材料如碳化钛TiC 组成)、氮化物陶瓷(一般由氮化硅Si3N4 和其他材料如氧化钇Y2O3 及氧化铝组成)。

Scope

This part of GB/T 15306 specifies the dimensions of indexable inserts made of ceramic cutting materials with rounded tool tip, fixed hole, 0° normal relief angle, U-level precision. These inserts are primarily clamped on turning and boring tool holders from the top. This standard applies to U-class non-hole indexable inserts made of various ceramic cutting materials. Ceramic cutting materials are composed of various oxides, nitrides, carbides and metals. For example, such ceramic materials are: oxide ceramics (mainly composed of alumina Al₂O₃), oxide-carbide ceramics (mainly composed of alumina and other materials such as iron carbide TiC ), nitride ceramics (generally composed of silicon nitride Si₃ where and other materials such as yttrium oxide ₂0₃ and alumina).
